ppc: Fix a warning in bcdcfz code and improve BCD_DIG_BYTE macro
This commit fixes a warning in the code "(i * 2) ? .. : ..", which
should be better as "i ? .. : ..", and improves the BCD_DIG_BYTE
macro by placing parentheses around its argument to avoid possible
expansion issues like: BCD_DIG_BYTE(i + j).
